SPARK-ARRESTER.

To all whom it ma 1 concern Be it. known that. 1,,Omnxno Smvnm' linxwnrr, a citizen. of the United States. residing at Moulton, in the county of Appanoose and State of lowa, have invented certain new and useful l lnprovements in Spark-Arresters; and I do declare the following to be a full. clear, and exact description of the invention. such as will enable others skilled in the art to which it apper tains to make and use the same.

This invention relates to improvements in spark arr-esters for smoke stacks.

()ue object of the invention is to provide a spark arrester having an improved means for receiving and retaining the sparks caught and deflected by the arr-ester.

Another object. is to PIOVltl. a spark arrester having an improved means for attaching and supporting the same in position on any form or smoke stack.

\Vith. thcse and. other objects in view. the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more tully described and claimed.

in the accompanying drawings: Figure 1 is a side view of my improved arrester showing the same applied to a stack: Fig. is a central vertical sectional view thereof; Fig. 3 is a. horizontal sectional view on the line 3-3 of Fig. 1; and, Fig. i is a detail view ot' the supporting band 01 the arrester.

My improved spark arrester comprises a cylindrical body portion 1 which is preterably t'ormed oi sheet metal and is of greater diameter than the stack to which the same is to be applied. The body portion 1 oi the arrester is disposed concentric with and spaced from the stack and is seclilrcd thereto by a series of set screws 2 arrz inged therein as shown. The lower end of the body 1 is o-tl'set inwardly to form an annular depending flange 3 and a. seat 4: to receive the upper edge of an annular member 5 forming a spark receiving chamber 5 which is arranged around the stack at the lower end of the body 1 as shown. The member 5 is formed in two semi-circular sections hinged together at one end as shown at- (i and pro vided at. their opposite ends with suitable fastening devices whereby said sections may be secured together around the stack and in engagement with the oilset lower end. of the body 1 as shown. .The outer or side walls of the sections of the member 5 are Specification of Letters Patent.

Patented May14, 1912. Serial No. 663,366.

inclined from the bottom 7 of the chamber toward its upper end thus increasing the width of the chamber at the bottom thereof and providing ample space for receiving the sparks caught and discharged therein by the deflecting mechanism oi the arrester. In one or both sections oi the member 5 near the bottom thereof is formed an opening through which the cinders may be removed from the chamber, said openings being normally closed by suitable doors 8 as shown. By thus constructing and arranging the member 5 it will be seen that the sections thereof may be opened or swung apart for the removal of the cinders or thatv the latter may be taken out through the door or doors 8. The cinder chamber 5 is supported in position below the body 1 by a supporting band or collar 9 which is preferably formed in two substantially semi-circular sections the ends of which are bent outwardly to form lugs '10 with which are engaged clamping bolts .11 whereby the. sections of the band or collar may be drawn together or clamped into tight engagement with the stack below the chamber 5 and in position to support the same in operative engagement with the lower end of the body 1. On the; upper edges of the sections of the band or eollar 9 are formed right angular radially projecting supporting lugs 12 which, together with the lugs 10 form a firm support; for the sections of the chamber 5.

Secured to the upper end of the body 1 of the deflector and spaced a suitable distance above the same and above the top of the stack is a cap 13, said cap having on its outer edge a downwardly curved annular flange 14. The cap 13 is supported above the body 1 and the-upper end of the stack by a plurality of supporting rods or standards 15, the upper ends of which are bolted or riveted to the flange 14 of the cap, while the lower ends are riveted or bolted to the upper portion of the body 1.

Concentrically arranged in the cap and secured to the inner side thereof is a s ark deflecting member 16 which is in the orm of an inverted cone and which projects downwardly to near the top of-the stack as shown. The diameter of the'flanged cap 13 is somewhat greater than that of the body 1 so that the standards 15 Here outwardly to a slight extent toward their upper ends as shown. Arranged around the standards 15 and secured at its upper edge catch and retain all sparks and cinders.

In the operation of the arrester, the sparks on leaving the stack strike the deflecting cone 16 and are deflected into the depending flange of the cap and are di rected downwardly by said flange and fall through the space between the body 1 and the stack into the spark chamber or receptacle 5 'at the lower end of the arrester from which the sparks and cixiders may be re moved in the manner described.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the .invention will be readily understood with- 'out requiring a -more extended explanation;

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle, or sacrificing any of the advan tages of the invention as claimed:

Having thus described my invention,

' what I claim is;

1. A spark arrester comprising a body portion adapted to be engaged with the upper end of a smoke stack and spaced therefrom to form a spark conduc ing passage, means engaged with the stacl to support and space said bodyfrom the stack, a spark receiving chamber formed of a bottomplate and hingedly connected sect-ions adapted to encircle the stack and be engaged with the lower end of the body to receive the sparks caught by the arrester, said sections being adapted tobeswung open to permit the discharge of the sparks received in the chamber, a supporting'c'ollar clamped around the stack and engaging said bottom plate to support said chamber in operative engagement with the lower end of the body of the arrcster,'and a spark catching and deflecting mechanism'arranged on the upper end of said body and over the'upper end of said stack. I

' 2. A spark arrester comprising a body portion adapted to be engaged with the upper end of a smoke stack and to form between the same and the outersideofsaid stack, a spark conducting passage, set screws arranged in said body and adapted to be engaged with the stack tosupport and space said body from the stack, a spark receiving chamber formed of a" bottom plate and hingedly connected sections adapted to be brought around the stack and in engagement with the lower end of the body to'receive the'sparks caught by the arrester, saidsections being adaptedto be swung open to permit the discharge of the sparks received by thechamber, doors arranged'in the chamber, a supporting collar clamped around the stack adjacent said bottom to support said chamber in operative engagement with the lower end of the body of the e arrester, and a spark catching and deflect. ing mechanism arranged on. the upper end of said body and over the upper end'of the stack.

3. A spark arrester comprising a body arranged on and spaced a suitable distance from the stack to form a spark conducting passage between the same and the outer side of the stack, an inwardly ofl'set depending flange on the lower end of the body,a spark,

receiving chamber i'ormed of a bottom plate and hingedly connected suitably fastened sections having inwardly inclined outer side walls, the upper edges of which are adapted to engage the oflset flange on the lower end of the body, a supporting collar formed in separable sections adapted to be clamped around the stack below and adjacent said bottom and having thereon lugs adapted to to support said spark receiving chamber, a cap arranged above the upper end of the stack, a series of supporting standards 'se-, cured to the upper end of the body and to said cap whereby the latter is held in position, an inverted spark deflecting cone secured. to the lnner s de of the cap and '21 screen covering arranged around said slandards to cover the space between the upper end of the body of the arrester and said cap.

In testimony whereof I have hereu'nto set my hand in presence of two subscribing witnesses,v I v ORLANDO SHIVELY BENNETT.
